Aluminum alters intracellular calcium homeostasis in vitro

1998

Gandolfi, L. | Stella, M.P. | Zambenedetti, P. | Zatta, P.

The present paper reports data regarding the influence of aluminum, at micromolar concentrations, on intracellular calcium homeostasis. Al3+ modifies Ca2+ uptake in the endoplasmic reticulum (ER), accelerates Ca2+ release from mitochondria and strongly inhibits Ca2+ -ATPase activity with a consequent high-level calcium accumulation inside the cell. These results suggest that Al3+ neurotoxicity may be related to an alteration of the intracellular calcium regulatory system.
